👉 Prechoroid is a term used in medicine and dentistry that refers to the outer layer of the anterior chamber of the eye, or the external part of the cornea. It is composed primarily of keratinocytes (cells that make up the skin) and contains a small amount of blood vessels, which are called "vessels." The prechoroidal layers provide protection for the lens and other structures in the eye, as well as allow for the formation of tears.
